DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In the following detailed description of the preferred embodiments,reference is made to the accompanying drawings which form a part hereof,and in which is shown by way of illustration specific embodiments inwhich the invention may be practiced.

Please refer to FIGS. 1, 2 and 3. FIG. 1 is an isometric view of apacking box 100 according to a first embodiment of the presentinvention, FIG. 2 is an isometric view of a cross-section A-A′ of FIG.1, and FIG. 3 is a top view of the cross-section A-A′ of FIG. 1.

The packing box 100 of the embodiment includes a top wall, a bottom wall101, four sidewalls 102, and at least four securing members. Thesidewalls 102 are mutually connected, that is, two adjacent sidewalls102 are mutually connected. The top wall and the bottom wall 101 arelocated at a top portion and a bottom portion of the packing box 100,respectively. Each of the securing members is arranged at an inner sideof a junction between the two adjacent sidewalls 102. The two adjacentsidewalls 102 can be mutually connected by means of forming one piece,or by a connector.

Each of the securing members includes a securing plate 103 and a shockabsorbing member 104. The securing plate 103 is perpendicular to thebottom wall 101. Two side ends of the securing plate 103 are connectedto the two adjacent sidewalls 102, respectively. The securing plate 103has a third surface. The third surface is a surface of the securingplate 103 opposite the junction. A first surface of the shock absorbingmember 104 is connected to the third surface of the securing plate 103.A limiting portion 1041 is formed at a second surface of the shockabsorbing member 104.

By the above technical scheme, when the packing box 100 containing thearticle falls onto the ground, a pressure (i.e., impact force) isapplied at one sidewall by the article through the shock absorbingmember 104. The impact force is dissipated by the securing plate 103. Apart of the dissipated impact force is withstood by another adjacentsidewall. Thus, the impact force applied by the article to the sidewalls102 is greatly reduced, thereby solving the problem of the sidewalls 102of the packing box 100 being damaged by a greater impact force.

In the packing box 100 of the embodiment, the side ends of the securingplate 103 have a bending portion, respectively. The bending portion isembedded in the sidewall 102. A plane of a tail end of the bendingportion is parallel to the sidewalls 102.

The bending portion is provided with at least one first screw hole. Eachof the sidewalls 102 is provided with at least one second screw hole.The first screw hole is aligned with the second screw hole. The tail endof the bending portion has the first screw hole. The first screw holeand the second screw hole are coupled together by a first screw 105.

The first surface of the shock absorbing member 104 has a first engagingportion. The third surface of the securing plate 103 has a secondengaging portion. The first engaging portion engages mutually with thesecond engaging portion. Specifically, the first engaging portion isconcave/convex, and the second engaging portion is convex/concave. Thatis, the first engaging portion is concave, while the second engagingportion is convex. Or the first engaging portion is convex, while thesecond engaging portion is concave.

The limiting portion 1041 is a groove, and a straight line located atthe groove is perpendicular to the bottom wall 101. A cross-section ofthe groove corresponds to a cross-section of one of the corners of thearticle contained in the packing box 100. For example, one of thecorners of the article is a right angle, while the groove is a dentategroove (i.e., the cross-section of the groove is tooth shaped and dentedinward).

The securing plate 103 includes a first substrate, a securinginterlayer, and a second substrate. The first substrate, the securinginterlayer, and the second substrate are stacked and combined, and thesecuring interlayer is sandwiched between the first substrate and thesecond substrate. For example, the first substrate and the secondsubstrate are respectively a metal plate, a plastic plate, or a plank,and the securing interlayer includes at least two metal meshes orplastic meshes. The metal meshes or the plastic meshes are stacked andcombined with each other. The surfaces of the first substrate and thesecond substrate that are contacted with the metal meshes or the plasticmeshes are embedded in the metal meshes or the plastic meshes.Specifically, a plurality of bumps are placed at the surfaces of thefirst substrate and the second substrate that are contacted with themetal meshes or the plastic meshes, and the bumps are embedded in themeshes of the metal meshes or the plastic meshes.

By sandwiching the metal meshes or the plastic meshes between the firstsubstrate and the second substrate, the greater impact force can berapidly dissipated by the metal meshes or the plastic meshes when thegreater impact force is applied at the securing plate 103, therebyreducing the greater impact force (or pressure) withstood by thesidewalls 102.

There is an angle between the securing plate 103 and one of the twoadjacent sidewalls 102. The angle is between 25 and 65 degrees. Forexample, the two adjacent sidewalls 102 include a first sidewall and asecond sidewall. For example, the two adjacent sidewalls 102 include afirst sidewall and a second sidewall. There is a first angle between thesecuring plate 103 and the first sidewall. There is a second anglebetween the securing plate 103 and the second sidewall. The angleincludes the first angle and the second angle. The examples of the angleare described as follows: (Example 1) the first angle of 25 degrees andthe second angle of 65 degrees, or conversely, the first angle of 65degrees and the second angle of 25 degrees; (Example 2) the first angleof 30 degrees and the second angle of 60 degrees, or conversely, thefirst angle of 60 degrees and the second angle of 30 degrees; (Example3) the first angle of 35 degrees and the second angle of 55 degrees, orconversely, the first angle of 55 degrees and the second angle of 35degrees; (Example 4) the first angle of 40 degrees and the second angleof 50 degrees, or conversely, the first angle of 50 degrees and thesecond angle of 40 degrees; and (Example 5) the first angle of 45degrees and the second angle of 45 degrees.

The shock absorbing member 104 is foamed plastic, rubber or corrugatedpaper. The shock absorbing member 104 contains solid particles, and thesolid particles are uniformly dispersed in the shock absorbing member104. The weight ratio or the volume ratio of the solid particles to theshock absorbing member 104 is from 0.2 to 0.8. For example, the weightratio or the volume ratio of the solid particles to the shock absorbingmember 104 is 0.2, 0.25, 0.28, 0.33, 0.37, 0.44, 0.47, 0.50, 0.53, 0.56,0.61, 0.65, 0.69, 0.72, 0.77, or 0.80. The shape of the solid particlescan be a sphere. Of course, the shape of the solid particles can also bea cube, a cuboid, or other regular or irregular cubes. The solidparticles can be metal particles, ceramic particles, plastic particles,and the like.

A second embodiment of the packing box 100 according the presentinvention is similar to the first embodiment. The second embodiment andthe first embodiment are different in that the shock absorbing member104 and the securing plate 103 are mutually fixed by at least one secondscrew.

A third embodiment of the packing box 100 according the presentinvention is similar to the first embodiment or the second embodiment.The third embodiment and the first embodiment (or the second embodiment)are different in that a glue layer is further sandwiched between thefirst surface of the shock absorbing member 104 and the third surface ofthe securing plate 103. The securing plate 103 and the shock absorbingmember 104 are fixed firmly to each other by providing the glue layerbetween the first surface and the third surface, thereby is advantageousthat a force applied by the shock absorbing member 104 is withstood bythe securing plate 103.
